Description

Technical Field

[0001] This utility model relates to a mixer, specifically a plow-type low-resistance mixer. Background Technology

[0002] During crystallization, the solid content gradually increases as the agitator is stirred. The solids will bury the agitator. The purpose of the agitator is to mix the materials and suspend the solid particles so that they do not settle.

[0003] When a regular oblique blade impeller is buried, the resistance becomes too great, preventing it from rotating. This can lead to motor overload or the impeller blades bending, deforming, or even breaking. Utility Model Content

[0004] To address the shortcomings of the prior art, this invention provides a plow-type low-resistance mixer. This invention employs an improved plow-type mixer with staggered blades. The plow-shaped blades feature a curved surface design, resulting in low resistance. Even when the mixer is completely submerged, it can still rotate normally, suspending solid particles.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a plow-type low-resistance mixer, comprising a central sleeve for mounting a stirring shaft, two stirring frames fixed on the central sleeve, the included angle between the two stirring frames being 166°, each stirring frame being fixed with multiple pear-shaped stirring blades, the working surface of the pear-shaped stirring blades being arc-shaped, and the front end of the pear-shaped stirring blades being lower than the rear end of the blades.

[0006] The angle e between the pear-shaped stirring blades and the radial surface of the stirring frame is 5°–10°.

[0007] It also includes a connecting rod, one end of which is fixed to the stirring frame and the other end of which is fixed to the non-working surface of the pear-shaped stirring blade.

[0008] In summary, this utility model achieves the following technical effects:

[0009] This invention employs an improved plow-type agitator with staggered blades. The plow-shaped blades feature a curved surface design, resulting in low resistance. Even when the agitator is completely buried, it can still rotate normally, suspending solid particles. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0016] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0020] Example:

[0021] Figure 1 This is a front view of a plow-type low-resistance agitator. Figure 2 yes Figure 1 Top view, Figure 3 yes Figure 1 3D image, Figure 4 yes Figure 1 The right view includes a central sleeve 1 for mounting a stirring shaft. The central sleeve 1 is fixed with two stirring frames 2, the included angle of the two stirring frames 2 is 166°, and each stirring frame 2 is fixed with multiple pear-shaped stirring blades 3. The working surface of the pear-shaped stirring blades 3 is arc-shaped, and the front end 31 of the pear-shaped stirring blades 3 is lower than the rear end 32 of the blades.

[0022] This invention employs an improved plow-type agitator with staggered blades. The plow-shaped blades feature a curved surface design, resulting in low resistance. Even when the agitator is completely buried, it can still rotate normally, suspending solid particles.

[0023] like Figure 1 As shown, the angle e between the pear-shaped stirring blade 3 and the radial surface of the stirring frame 2 is 5°–10°.

[0024] In this embodiment, e is 7°.

[0025] It also includes a connecting rod 4, one end of which is fixed to the stirring frame 2 and the other end is fixed to the non-working surface of the pear-shaped stirring blade 3.

[0026] The two mixing racks 2 are symmetrically arranged at an angle of 166°. The mixing racks 2 are tilted upwards from the inside out, so that the arc surface of the pear-shaped mixing blades 3 is tilted, reducing resistance.

[0027] In one embodiment, the cross-section of the pear-shaped stirring blade 3 is a quarter circle, and it is tangent to the horizontal plane and the vertical plane respectively.

[0028] In another embodiment, combined with Figure 3 and Figure 4The angle from the outer side to the inner side of the blade tip 31 gradually decreases.

[0029] Specifically, the outer side of the blade tip 31 forms an angle α with the horizontal plane of 10°–20°, and the inner side forms an angle b with the horizontal plane of 3°–8°.

[0030] In this embodiment, a is 12° and b is 5°, forming a pattern with the outer side higher than the inner side. Combined with the arc-shaped structure of the entire working surface, it forms a pear-shaped structure, which can scoop up the crystallized material and then transport it upwards with the arc-shaped surface to form a stirring and more uniform mixing.

[0031] like Figure 3 As shown, the angle from the outer side to the inner side of the blade rear end 32 gradually increases.

[0032] The outer side of the blade rear end 32 forms an angle c with the vertical plane of 0°–5°, and the inner side forms an angle d with the vertical plane of 5°–12°.

[0033] In this embodiment, c is 0° and d is 8°, forming a pattern with the outside facing forward and the inside facing backward, which can transport materials upward and inward. Combined with the arc-shaped surface structure, the resistance is smaller.

[0034] In this embodiment, a stirring rack 2 is equipped with 3 pear-shaped stirring blades 3.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
